Natural Gas LPG Diesel Oil Fired Hot Water Boiler for Hotel Restaurant Room Residential Heating

WNS series full automatic hot water boiler adopts horizontal three return wet back structure, and avoid the problems that the smoke box of the dryback, and central backflash system could be sealed and the temperature of the smoke box could be too high.The furnace is made of advanced structure, corrugated furnace, which increases the heat transfer area and stability of the furnace.The smoke pipe adopts the high efficient heat transfer fitting, the thread smoke tube, which improves the heat transfer coefficient of the smoke tube.

The combustion chamber adopts the waveform internal furnace or the direct-shape internal furnace,and the wet back structure with buffwelding,thus avoding the characteristic that the back tube board is easy to be burnt out caused by the flushing of high temperature smoke gas,and ensuring the safety running of the boiler.

The smoke gas adopts the three-return design,and the smoke tube adopts the spiral spirally corrugated tube:the tubolator is inserted inside the smoke tube,thus increasing the convection heat transfer area and enhancing the heat transfer effect,the condersing heat exchange can be additionally arranged at the sensible heat and latent heat in the smoke gas,thereby improving the thermal efficiency of the boiler(95%)

Boiler Features:

1.Monitoring of water level: Equipped with water level electronic detector to control the water level.

2.Setting time: The users can set the starting and stopping time as their demand.

3.Electric leakage protection: When the elements of boiler have a electric leakage, the control system will cut off power automatically.

4.Water shorage protection: When the boiler is lack of water, the system will turn off burner and raise alarm.

5.Over pressure protection:When the pressure of boiler is over your setting point, burner will stop working and raise alarm.

6.Power abnormal protection:When the power ia abnormal, the boiler will stop working immediately.
